6. Troubleshooting

6.1 No Signal / Black Screen

• Check Power: Ensure both the Transmitter (TX) and Receiver (RX) units are properly powered. The RX unit specifically requires sufficient power (5V 2A) and should be powered first before connecting the HDMI/USB-C cable to the display.
• Cable Connections: Verify that all HDMI and USB-C cables are securely connected to their respective ports on the devices and displays.
• Source Device Output: Confirm that your source device (PC, game console) is outputting video correctly. Try connecting the source device directly to the display with a cable to rule out issues with the source.
• Display Input: Ensure your display (TV, monitor, projector, AR glasses) is set to the correct input source (e.g., HDMI 1, USB-C).
• Restart Devices: Disconnect power from both TX and RX units, then reconnect. Also, restart your source device and display.

6.2 Intermittent Signal / Flickering

• Distance and Obstacles: Reduce the distance between the TX and RX units. Ensure there are no significant physical obstructions (walls, large furniture) between them that could interfere with the wireless signal.
• Interference: Keep the units away from other wireless devices (e.g., Wi-Fi routers, cordless phones, microwave ovens) that operate on similar frequencies.
• Power Supply: Ensure stable and sufficient power supply to both units. Fluctuations in power can affect signal stability.

6.3 No Audio

• Source Audio Settings: Check the audio output settings on your source device to ensure audio is being sent via HDMI.
• Display Audio: Verify that the audio on your display device (TV, monitor, AR glasses) is not muted and the volume is turned up.
• Cable Integrity: Ensure the HDMI or USB-C cable connecting the RX to the display is not damaged.

6.4 AR Glasses Compatibility Issues

• Firmware Update: As mentioned in the setup, some AR glasses (e.g., Nreal) may require a firmware update to work correctly with external video sources. Consult your AR glasses manufacturer's support.
• Power to RX: Ensure the RX unit is adequately powered, especially when connecting to power-hungry AR glasses.
• USB-C Cable: Use a high-quality USB-C cable that supports video transmission.
